Description

用于车身后部的加强结构
相关申请的交叉参考
本申请要求于2019年11月28日提交中国专利局、申请号为2019111921756、名称为“一种用于车身后部的加强结构”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及汽车上车体结构技术领域，尤其涉及一种用于车身后部的加强结构。
背景技术
在现有的Cross(跨平台跨功能)与轿车车型结构中，C柱上端加强装置为二通中空或三通中空结构，其中二通中空结构具有两个端部，一个端部连接B柱上边梁加强板的后段，另一端部连接D柱上内板，在整车X向形成一个有效的腔体面积。三通中空结构具有三个端部，它在二通中空结构的基础上，增加了一个端部来连接顶盖后横梁，从而在整车X、Y向形成了有效腔体面积。
Cross(跨平台跨功能)与轿车车型由于车身后顶部比较低，因此整车Z向支撑比较重要，而现有二通或三通中空结构仅在整车X与Y向形成有效的截面腔体，对整车Z向的支撑不够。同时，现有的二通或三通中空结构与车身后部的其他结构未能形成一个闭环传力路径，不利于车身后部结构力的分散，如果增加其他的加强部件来分散力，势必会增加车身质量。进一步地，汽车底盘的力通过减震器安装板加强板传递到后轮罩外板，到C柱上端加强装置时力的传递路径才开始出现分支，因此减震器安装板加强板所受外力较大，容易导致减震器安装板加强板与后轮罩外板的焊点开裂。
发明内容
针对上述缺陷，本公开的目的是提供一种用于车身后部的加强结构，以满足改进后的车型后部的性能与轻量化需求。
本公开提供了一种用于车身后部的加强结构，包括设置在C柱内板外侧的C柱上加强板和C柱下加强板，以及后轮罩外板、后轮罩内板和减震器安装板加强板，C柱上加强板为三通中空结构，其具有三个端部，其中第一端部与B柱上边梁加强板相连接，第二端部与C柱下加强板的上端相连接，第三端部与顶盖后横梁相连接；C柱下加强板为中空结构，其下端与后轮罩外板相连接，且位于减震器安装板加强板的延伸路径上。
优选地，C柱上加强板的第三端部上设有后背门铰链加强板。
优选地，后轮罩内板的内侧设有后轮罩加强板，后轮罩加强板和C柱内板之间设置有后排安全带下安装板。
优选地，后排安全带下安装板设置在减震器安装板加强板的延伸路径之外。
优选地，C柱下加强板位于减震器安装板加强板的Y向延伸路径上。
优选地，C柱上加强板和C柱下加强板均焊接在C柱内板上。
优选地，C柱内板与D柱上内板、侧围后部连接板之间焊接连接。
本公开的有益之处在于：
1、C柱上加强板与C柱内板之间形成了腔体截面结构，并分别与C柱下加强板、顶盖后横梁和B柱上边梁加强板的后段焊接，因此C柱上加强板分别在整车Z向、Y向两个受力方向形成一个内外对应的盒装结构，有效提高了C柱上加强板处结构的刚度、模态，利于车身的轻量化设计；
2、C柱上加强板为三通接头一体化成型件，可以有效地减少工艺与材料成本；
3、在C柱上加强板与减震器安装板加强板之间形成了一个闭环传力路径，可以有效地传递底盘的力，避免车身因应力集中而产生疲劳耐久问题。

本公开的较佳实施方式
下面结合附图对本公开的具体实施方式作进一步详细说明。这些实施方式仅用于说明本公开，而并非对本公开的限制。
在本公开的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、 “左”、“右”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本公开的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本公开中的具体含义。
图1所示为本公开的加强结构的主视图，在以下的描述中，以图1中的附图作为方向的参考基础，垂直于视图纸面朝外为左方向，垂直于视图纸面朝内为右方向，沿视图纸面向上为上方向，沿视图纸面向下为下方向，沿视图纸面朝右为后方向，沿视图纸面朝左为前方向，其中，定义上下方向为Z轴方向，左右方向为Y轴方向，前后方向为X轴方向。“外侧”指的是后轮罩外板21所在的一侧，“内侧”指的是后轮罩内板22所在的一侧。
如图1-5所示，本公开提供了一种用于车身后部的加强结构，应用于Cross车型与轿车车型，该加强结构包括C柱上加强板11、C柱下加强板12、C柱内板13、后轮罩外板21、后轮罩内板22和减震器安装板加强板5，C柱内板13与D柱上内板7、侧围后部连接板6焊接连接。其中作为C柱上端加强装置的C柱上加强板11为三通中空结构，其具有分别向三个方向延伸的三个端部，其中第一端部111向前方延伸，与B柱上边梁加强板31相连接；第二端部112向下方延伸，与C柱下加强板12的上端相连接；第三端部113向右侧延伸，与顶盖后横梁8相连接。具体地，第三端部113上还焊接有后背门铰链加强板4，为后背门提供铰链安装孔，满足铰链安装点的强度要求。C柱上加强板11焊接在C柱内板13外侧，并与C柱内板13之间形成三通空腔。这样的中空结构不仅可增加车身后部的模态、强度和刚度，而且有利于传递、分散冲击力，将外力较快地通过三个端部分散至其他连接部件上，减少车身后部所受到的冲击变形，延长车辆的使用寿命。
作为C柱下端加强装置的C柱下加强板12同样为中空结构，其焊接在C柱内板13外侧并与C柱内板13之间形成空腔。其下端焊接在后轮罩外板21上，且位于减震器安装板加强板5的Y向延伸路径上。这里的“Y向延伸路径”具体地指的是C柱下加强板12和后轮罩外板21在减震器安装板加强板5所对应的Y向投影位置处焊接连接。这样设置的C柱下加强板12既可以提供Z向支撑，又有助于与减震器安装板加强板5之间形成闭环传力路径。在具体实施中，减震器安装板加强板5与后轮罩外板21、后轮罩内板22组成空腔结构，并焊接固定在后轮罩内板22的外侧，而在后轮罩内板22的内侧的对应位置则焊接固定有后轮罩加强板23，减震器安装板加强板5、后轮罩内板22和后轮罩加强板23之间通过三层焊直接焊接为一体。
如图6所示，优选地，后轮罩加强板23上还焊接有后排安全带下安装板9，后排安全带下安装板9同时焊接在C柱内板13的内侧，并设置在减震器安装板加强板5的延伸路径之外。这样设置不仅为安全带提供了安全牢固的安装位，还可以将安全带的受力沿后轮罩加强板23的布置路径传递并分解到车身后部的受力件上，同时也提高了C柱的受力能力。
在车辆运动时，如图7和图8所示，底盘的力的传递路径如下：减震器安装板加强板5→后轮罩内板22→后轮罩加强板23和后排安全带下安装板9→C柱内板13和后轮罩外板21→C柱下加强板12→C柱上加强板11→顶盖后横梁8、B柱上边梁加强板31和B柱上内板后段32，即在C柱上加强板11与减震器安装板加强板5之间形成了一个闭环传力路径，可以有效地传递底盘的力，避免车身因应力集中而产生疲劳耐久问题。同时传递到减震器安装板加强板5的力会在此之后被各个相互连接的受力部件不断分散，大大降低了减震器安装板加强板5与后轮罩外板21之间焊点开裂的风险。
综上所述，本公开的有益之处在于，C柱上加强板11与C柱内板13之间形成了腔体截面结构，并分别与C柱下加强板12、顶盖后横梁8和B柱上边梁加强板31的后段焊接，因此C柱上加强板11分别在整车Z向、Y向二个受力方向形成一个内外对应的盒装结构，有效提高了C柱上加强板11处结构的刚度、模态，利于车身的轻量化设计。同时，C柱上加强板11为三通接头一体化成型件，可以有效地减少工艺与材料成本。
以上所述仅是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本公开的保护范围。。
